No, the manufacturer does not save on wood costs. The thickness reduction of 1/32" is due to the slight surface sanding done to bring each panel at time of manufacture to a common thickness. Variations in the individual veneer thicknesses at time of panel manufacture account for variations in individual panel thickness, hence light sanding of each panel to bring the panel to a common thickness. I will not get into the discussion of why 2x4's are 1-1/2" x 3-1/2" today as that is a much longer story usually only understood by someone who has a history over many decades in the lumber manufacturing business here in North America.

No it's not...common thickness was 3/4". It was also sanded depending on grade. I used to use a full 3/4" , 1/2" 1/4" dado blades and router bits yrs ago, (sanded furniture grade plywood) Now I have to use router bits specifically made for the 1/32" less. Or shim up on dado blades. And 2x4's are 1-9/16" x 3-9/16"
